An investigation into sexual orientation discrimination as an explanation for wage differences

This study explores the effects of sexual orientation on earnings. It is found that, ceteris paribus, men living with male partners tend to earn less than other men, and women living with female partners tend to earn more than other women. These earnings differentials tend to vary by region. They also vary by education and occupation for men, and with the presence of minor children for women. In addition, the age-earnings profiles of women living with female partners tend to be higher, flatter, and less concave than those of other women.
